I just replaced all the tubes in my 3 channel Triple Rectifier with new tubes from Mesa Boogie. I turned the amp on and immediately blew a fuse. After a bit of trial and error and tube swapping from new back to old, I realized it was a bad rectifier tube.
Since then, there has been a dramatic loss of gain in all three channels. To put it in perspective, Channel 3 in the modern setting with the gain at 2 o'clock sounds like Malcolm Young's slightly distorted rhythm guitar, which is a great tone, don't get me wrong, but not what I bought a Triple Rec for.
I opened the amp up and checked for burned components, cold solder joints, etc., but couldn't find anything. I checked the bias with my bias probe and am getting 14 mV which seems to be normal for a Triple Rectifier.
Does anyone have any ideas as to what's going on? Any and all help is appreciated. Thanks.
UPDATE: Thanks to Tien and the great people at Boogie, I'm sorted.
